ELIE W. L ABOMBARDE, 0F NASHUA, NEW HAMPSHIRE.

Application filed January 11, 1923. Serial No. 611,952.

To all whom it may concern:

Be it known that I, ELIE W. LABOMBARDE, of Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements "in Paper Receptacles and Methods of Making the Same, of which the following is aspecification.

This invention relates to boxes, and has articular reference to that type sometimes iznown as beriy boxes or fruit baskets. Such boxes have usually been made of thin wood or veneering which is neither strong'nor water-proof. As is well known, the juice or stain of berries readily passes through and escapes from the ordinary berry boxes or fruit baskets.

The object of" my invention is to provide a moisture-proof paper box for the abovementioned uses, which box shall be of low cost and yet very strong.

My invention consists in the box or receptacle, and in the method of making it, substantially as hereinafter described and claimed. 7

Of the accompanying drawings Figure 1 is a plan view of the preferred form of paper blank, before any folding has been imparted to it.

Figure 2 is a perspective view of the box or receptacle in its completely folded and secured condition.

Figure 3 represents a section on the line 33 of Figure 2.

Similar reference characters indicate similar parts in all of the views.

The blank from which the box or receptacle is made comprises a central rectangular portion 12 which is to form the bottom of the box or basket, the blank being slitted and being also creased as indicated by dotted lines in Figure 1, to form side or wall portions 13, 14, 15, 16. The portions 15 and 16 have flaps 17, extending laterally from the ends thereof, and all of the side or wall portions 13, 14, 15 and 16, have outer narrow extensions as indicated at 18 in Figure 1. Said narrow extensions are all folded over and adhesively secured to the portions from which they extend to constitute reinforced or double-thick edges of the side walls of the box as indicated in Figures 2 and 3.

The wall portions 15, 16, are provided with openings of slot formation as indicated at 19, and the central or bottom portion 12 has a plurality of small holes 20, said openings and holes providing for the ventilation which is desirable in berry .boxes and fruit the box and thereby provide for ample ven-' itilation through the holes 20. In this connection it is to be noted that the portions 13 and 14 are longer (in the direction'away from the portion 12) than the portions 15, 16, by an amount equalling the width of the portions 21, This is to compensate for the amount necessary to provide the ribs or legs when the blank is folded, and ensure equal height of allfour walls of the box.

The material of which the blanks are made is cheap paper stock or what is known as paper board. The blanks are out before receiving any moisture-proofing treatment. In order that the blanks shall be rendered moisture-proof so that, when converted to box or basket form, access of moisture from the outside through the bottom or sides of the box, or leakage of juice of berries or fruit through the bottom or sides, will be prevented, I preferably employ paraffine.

I do not limit myself to the use of the particular material known as parafHne, but shall employ that term for convenience of description and not for the purpose of limitation.

The most economical way to make paper boxes from blanks is to fold the blanks with overlap-ping portions thereof secured together by glue. Aswill presently be explained,

glue is employed in the production of my improved boxes. But since the presence of paraffine on the surface of paper or paper board greatly interferes with glue as an adhesive to reliably secure overlapping portions together, I so treat the blanks, after the} are cut and before folding, that they are amply impregnated with paraifine to be moisture-proof and yet have surfaces so free from parafiine that an adhesive such as high grade or pure hide glue, or gelatine, will hold overlapping portions in permanently secured condition. The preferable-method by which I accomplish the results stated is as follows The paper board blanks, while fiat as indicated in Figure 1, are fed between squeeze rolls which are suitably sup-plied with melted paraifine, the rolls being so close together 17 and to the extensions 18, and to narrow portions in the form of stripes across the wall portions 13, 14, close to the crease lines 6. In Figure 1 the shading indicates Where the glue is applied as just'described. Then the portions or extensions 18 are folded in fiat onto the Wall portions from which they extend and are subjected to pressure to cause them to permanently adhere in the folded condition indicated in Figure 2-. Then the two wall portions 13, 14, are folded toward each other on the crease lines b, against the central portion 12, and subjected to suflicient pressure to squeeze the narrow stripes'of glue near the crease lines 7) onto the nortions 21. Next, the wall portions 13, 14, are swung to nearly upright positions, the turning or swinging being on the crease lines a, the narrow portions 21' of course turning down and forming rib-shaped legs because they arestuck to the inner areas of the said wall portions. The adhesive securing together of the portions of the walls 13, 14, which form the rib-shaped legs renders said legs permanent so they can not unfold or flatten down. Therefore, since only twoof the said walls have the said legs, air can always have free access to the ventilated bottom from either side through spaces the full width of the other two walls 15, 16. After the portions 13, 14, have been turned v or swung up as just described, the other two wall portions 15, 16, are turned up and their glued flaps 17 overlapped upon or onto the outer surfaces of the portions 13, 14, and

subjected to pressure to cause them to adhere and remain in the positions shown in Figure 2. The box or receptacle is now complete and ready for any ordinary use, but T may, if desired, add suitable fastenings such as staples indicated at 0 in Figure 2. As shown by Figures 2 and 3 the folding in of the extensions 18 not only results in reinforcing the upper edges of the walls of Having now described my; invention, it

A paper receptacle comprising a bottom portion having ventilating openings, and four side portions or walls integral with the bottom portion, two of said walls which are opposite each other having ventilating openings, and the other two walls having doubled narrow portions projecting below the ve ttilated bottom and forming rib-shaped legs, all of said walls having doubled upper edges, the two walls which are provided with ventilating openings having flaps folded over and secured to the outer surfaces of the other two walls above the rib-shaped legs thereof whereby air can have free access to the ventilated bottom from either side below the two ventilated walls the full width of said bottom.

In testimony whereof I have affixed my signature.
